Specifying E-Mail Addresses
Associate a valid e-mail address and definition with each user who receives messages generated by the system.
See Building an E-Mail System Interface
E-mail can be used with many features. For example:
System administrators can receive automatic notification when user IDs are deactivated because of log-in violations.
Based on a Security Control setting, users can receive system-generated passwords by e-mail.
Note: If you plan to use this feature, be sure to specify e-mail data when you set up user accounts so that users can receive their passwords.
Enhanced Controls uses e-mail to inform administrators of unusual audit trail and electronic signature events.
